Alexey Khoroshilov 2dd34339ac xen-netback: do not report success if backend_create_xenvif() fails 
If xenvif_alloc() or xenbus_scanf() fail in backend_create_xenvif(),
xenbus is left in offline mode but netback_probe() reports success.

The patch implements propagation of error code for backend_create_xenvif().
